How to enable the Alt + right click shortcut (select edge loop) in Lubuntu?
To disable the shortcut on Lubuntu open the file manager and at the path line copy and past this: ~/.config/openbox/
Open the file lubuntu-rc.xml (you can use Leafpad) and delete the following lines:


  &lt;mousebind button="A-Right" action="Press"&gt;
    &lt;action name="Focus"/&gt;
    &lt;action name="Raise"/&gt;
    &lt;action name="Unshade"/&gt;
  &lt;/mousebind&gt;
  &lt;mousebind button="A-Right" action="Drag"&gt;
    &lt;action name="Resize"/&gt;
  &lt;/mousebind&gt;



Then save the file, open the terminal (Ctrl+Alt+T) and type this:

sudo openbox --restart
